Saints and Namedays Calendar. These are special dates which are usually defined in Catholic countries. Every day of the year is assigned the name of a Saint. For example July 12th is always "Saint Olivier". Namedays are mainly defined in Scandinavian countries. Namedays are similar to saints but usually carry no religious significance : In some Scandinavian countries, you must use one of the available namedays of the calendar to name your child; you cannot choose from outside this list. In some countries the list of namedays changes from year to year, in some countries there can be one, two or as many as eight names in a given day.
